The present invention relates to a substance(s) deposition control device for an offset printing system, characterized in that it comprises:—at least one offset plate intended to receive a wetting liquid and a coloured substance in succession,—at least one controlled-deposition means for each offset plate, the deposition means comprising at least one deposition head spraying at least one wetting solution and at least one deposition head spraying a defined coloured substance,—at least one means for cleaning the offset plate, and in that the covering of the offset plate or plates comprises a mesh structure defined by a plurality of hydrophilic and lipophilic individual surfaces capable of receiving a controlled deposition of wetting liquid and/or coloured substance, each of these hydrophilic and lipophilic surfaces being separated from its direct neighbours by at least one hydrophobic and lipophobic peripheral surface. |

1. A matter(s) deposition control device for an offset printing system (0) comprising:
at least one offset plate (2, 2a, 2b, 2c) configured to receive successively a wetting liquid and a coloured matter, at least one controlled deposit means (1, 1a, 1b, 1c) for each offset plate (2, 2a, 2b, 2c), the deposit means (1, 1a, 1b, 1c) comprising at least one deposit head projecting at least one wetting solution and at least one deposit head projecting a defined coloured matter, at least one cleaning means (6a, 6b, 6c) of the offset plates (2, 2a, 2b, 2c),and a coating of the offset plate(s) (2, 2a, 2b, 2c) comprises a mesh structure defined by a plurality of hydrophilic and lipophilic unit surfaces (9, 9a, 9b) configured to receive controlled deposit of wetting liquid and/or coloured matter, each of these hydrophilic and lipophilic surfaces being separated from its direct neighbours by at least one peripheral hydrophobic and lipophobic surface (8). |
